Black-and-white cookies Oversize and like a nearly flat iced cupcake, the black-and-white has been a staple at Glaser’s bakery since 1902. In the "Dinner Party" episode, Jerry Seinfeld says, “The key to eating a black and white cookie, Elaine, is you want to get some black and some white in each bite. Nothing mixes better than vanilla and chocolate. And yet, still, somehow racial harmony eludes us. If people would only look to the cookie. All our problems would be solved.” 87th St. and First Ave.; tel. 1 212 289 2562. www.glasersbakeshop.com.
